Description

1. Technical Field
The present disclosure relates to a hinge assembly, and particularly to a hinge assembly employed in an electronic device.
2. Description of Related Art
Collapsible electronic devices, such as notebook computers, are popular for their portability. In the collapsible electronic device, a cover is hinged on a main body via a typical conventional hinge assembly.
The typical conventional hinge assembly often includes a shaft, a revolving bracket, a fixing bracket, a friction member, a resilient member, and a fastening member. The revolving bracket, the fixing bracket, the friction member, and the resilient member are sleeved on the shaft. The fastening member is fixed on the shaft. Each of the revolving bracket and the fixing bracket includes a contact surface. One of the contact surfaces forms a protrusion, and the other contact surface defines a slot for receiving the protrusion. In use, the revolving bracket rotates relative to the fixing bracket, the protrusion withdraws from the slot to resist the contact surface and deform the resilient member. Friction force generated between the components of the hinge assembly allow the revolving bracket to maintain the respective desired positions relative to the fixed bracket.
However, with use, the friction force is diminished due to aging of the resilient member.
Therefore, there is room for improvement within the art.
The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the views.

engaging portion
164. In the illustrated embodiment, the assisting
portion
1624 is an arcuate recess defined in the
main body
162 and communicates with the
receiving slot
1622. The
engaging portion
164 is a silicone gasket to prevent abrasion while fixing an electronic device to the
protective member
16.
The
resilient member
17 may be a substantially disk-shaped elastic member defining a through
hole
172. The through
hole
172 corresponds in shape and size to a cross section of the
shaft portion
144, such that the
resilient member
17 may be sleeved on the
shaft portion
144.
The
washer
18 may be substantially disk-shaped and defines a through
hole
182. The through
hole
182 corresponds in shape and size to the cross section of the
shaft portion
144, such that the
washer
18 may be sleeved on the
shaft portion
144. The
washer
18 further defines
several oil holes
184 aligned around the through
hole
182.
The fastening
member
19 may be a nut defining a threaded
hole
192. The fastening
member
19 has a
friction portion
194 formed at an end. In the illustrated embodiment, the
friction portion
194 includes several protrusions protruding from an end surface of the
fastening member
19.
Also referring to
FIG. 3
, the
shaft portion
144 of the
pivot shaft
14 passes through the
pivot hole
1242 of the fixing
bracket
12, the through
hole
1522 of the revolving
bracket
15, the through
hole
172 of the
resilient member
17, and the through
hole
182 of the
washer
18, in that order. The
positioning protrusion
1526 is received in the
positioning recess
1244 adjacent to the mounting
portion
122. The restricting
protrusion
126 is received in the curved restricting
slot
1524, and a sidewall defines the curved restricting
slot
1524 abutting an end of the restricting
protrusion
126 adjacent to the mounting
portion
122. The
fastening member
19 is threaded onto the
pivot shaft
14 and resists the
washer
18. The
swing arm
154 is securely received in the
receiving slot
1622, and the assisting
portion
1624 corresponds to the
rotary portion
152 of the revolving
bracket
15.
In a first state, the
positioning protrusion
1526 is received in the
positioning recess
1244 adjacent to the mounting
portion
122, and the
contact surface
1241 of the fixing
bracket
12 abuts the
contact surface
1521 of the revolving
bracket
15. Referring to
FIG. 4
, when the revolving
bracket
15 rotates relative to the fixing
bracket
12, the
positioning protrusion
1526 withdraws from the
positioning recess
1244 adjacent to the mounting
portion
122, and the
positioning recess
1244 resists the
contact surface
1241 of the fixing
bracket
12 and deforms the
resilient member
17. An amount of axial force is generated between the components of the
hinge assembly
100. When the revolving
bracket
15 is rotated further, the
positioning protrusion
1526 is received in the
positioning recess
1244 away from the mounting
portion
122, and an opposite sidewall defining the curved restricting
slot
1524 abuts an end of the restricting
protrusion
126 away from the mounting
portion
122, such that the revolving
bracket
15 is prevented from rotating any further and the revolving
bracket
15 reaches a maximum opening position, and the
hinge assembly
100 is in a second state.
The revolving
bracket
15 may achieve a plurality of different opening positions relative to the fixing
bracket
12 by receiving the
positioning protrusion
1526 in
different positioning recesses
1244, thereby avoiding the sliding of the revolving
bracket
15 relative to the fixing
bracket
12 due to the aging of the
resilient member
17.
The revolving
bracket
15 and the fixing
bracket
12 are the same or similar materials so as to avoid abrasion when the revolving
bracket
15 is rotated relative to the fixing
bracket
12, such that the service life of the
hinge assembly
100 can be prolonged.
Alternatively, the
positioning protrusion
1526 may be instead formed on the
contact surface
1241 of the fixing
bracket
12, and the positioning recesses 1244 defined in the
contact surface
1521 of the revolving
bracket
15 accordingly.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages.
